suitable for outdoor use reduces the risk of electric shock.  
3. Personal safety  
WARNING. When using power tools, basic safety  
precautions should always be taken to reduce the risk of  
fire, electric shock and personal injury. Also, please read  
and heed the advice given in the additional important  
safety instructions.  
a. Stay alert, watch what you are doing and use  
common sense when operating a power tool.  
Do not use a power tool while you are tired or under  
the influence of drugs, alcohol or medication. A moment  
of inattention while operating power tools may result in  
serious personal injury.  
Save these instructions  
1. Work area  
b. Use safety equipment. Always wear eye protection.  
Safety equipment such as dust mask, non-skid  
safety shoes, hard hat, or hearing protection used for  
appropriate conditions will reduce personal injuries.  
a. Keep work area clean and well lit. Cluttered and dark  
areas invite accidents.  
b. Do not operate power tools in explosive  
atmospheres, such as in the presence of flammable  
liquids, gases or dust. Power tools create sparks which  
may ignite the dust or fumes.  
c. Avoid accidental starting. Ensure the switch is in the  
off position before plugging in. Carrying power tools with  
your finger on the switch or plugging in power tools that  
have the switch on invites accidents.  
c. Keep children and bystanders away while operating a  
power tool. Distractions can cause you to lose control.  
d. Remove any adjusting key or wrench before  
turning the power tool on. A wrench or a key left  
attached to a rotating part of the power tool may result  
in personal injury.  
2. Electrical safety  
a. Power tool plugs must match the outlet. Never  
modify the plug in any way. Do not use any adapter  
plugs with earthed (grounded) power tools.  
Unmodified plugs and matching outlets will reduce risk  
of electric shock.  
e. Do not overreach. Keep proper footing and balance at  
all times. This enables better control of the power tool in  
unexpected situations.  
f. Dress properly. Do not wear loose clothing or  
jewellery. Keep your hair, clothing and gloves away from  
moving parts. Loose clothes, jewellery or long hair can be  
caught in moving parts.  
b. Avoid body contact with earthed or grounded  
surfaces such as pipes, radiators, ranges and  
refrigerators. There is an increased risk of electric shock  
if your body is earthed or grounded.

g. If devices are provided for the connection of dust  
extraction and collection facilities, ensure these are  
connected and properly used. Use of these devices  
can reduce dust related hazards.  
5. Service  
a. Have your power tool serviced by a qualified repair  
person using only identical replacement parts. This  
will ensure that the safety of the power tool is maintained.  
4. Power tool use and care  
Additional safety rules for air compressors  
a. Do not force the power tool. Use the correct power tool  
for your application. The correct power tool will do the job  
better and safer at the rate for which it was designed.  
WARNING. Before connecting a tool to a power source  
(mains switch power point receptacle, outlet, etc.) be sure  
that the voltage supply is the same as that specified on the  
nameplate of the tool. A power source with a voltage greater  
than that specified for the tool can result in serious injury to  
the user, as well as damage to the tool. If in doubt, do not  
plug in the tool. Using a power source with a voltage less  
than the nameplate rating is harmful to the motor.  
b. Do not use the power tool if the switch does not turn  
it on and off. Any power tool that cannot be controlled  
with the switch is dangerous and must be repaired.  
c. Disconnect the plug from the power source before  
making any adjustments, changing accessories, or  
storing power tools. Such preventive safety measures  
reduce the risk of starting the power tool accidentally.  
Always remove the plug from the mains socket before  
making any adjustments or maintenance.  
d. Store idle power tools out of the reach of children  
and do not allow persons unfamiliar with the power  
tool or these instructions to operate the power tool.  
Power tools are dangerous in the hands of untrained users.  
To reduce the risk of fire or explosion, never spray  
flammable liquids in a confined area. It is normal for  
the compressor motor and pressure switch to produce  
sparks during use. If sparks come into contact with petrol  
vapours or solvents, they may ignite the vapours and  
cause a fire or explosion.  
e. Maintain power tools. Check for misalignment or  
binding of moving parts, breakage of parts and  
any other condition that may affect the power tools  
operation. If damaged, have the power tool repaired  
before use. Many accidents are caused by poorly  
maintained power tools.  
Do not operate this compressor in the presence of  
explosive gases, due to the risk of explosion. Check all  
working conditions and surrounds before turning the  
compressor on. Pay special attention when operating the  
compressor in a boat, pit or in any location where there is  
not a constant flow of fresh air.  
f. Keep cutting tools sharp and clean. Properly  
maintained cutting tools with sharp cutting edges are less  
likely to bind and are easier to control.  
Always operate the compressor in a well ventilated area.  
Do not smoke while spraying. Do not spray where sparks  
or flames are present. Keep the compressor as far away  
from the spray area as possible.  
g. Use the power tool, accessories and tool bits etc.,  
in accordance with these instructions and in the  
manner intended for the particular type of power  
tool, taking into account the working conditions and  
the work to be performed. Use of the power tool for  
operations different from those intended could result in a  
hazardous situation.  
The solvents trichloroethane and methylene chloride can  
chemically react with the aluminium used in some paint  
spray guns and form an explosion. If these solvents are  
used, ensure that only stainless steel spray equipment is  
connected. The compressor is not affected by the use of  
these solvents.

Never directly inhale the compressed air produced  
by a compressor and do not use it for charging  
breathing tanks.  
Keep the compressor at least 300mm from the nearest  
wall to ensure adequate ventilation for cooling purposes.  
Before transporting the compressor make sure that  
the pressurized air is bled from the tank and that the  
compressor is firmly secured.  
Do not use welding equipment in close proximity to the  
compressor. Do not weld anything to the air tank of the  
compressor: this could dangerously weaken the tank and  
will void the warranty.  
Protect the air hose and cord set from damage. Inspect  
for weak or worn spots regularly and replace if necessary.  
Do not use the compressor outdoors when it is raining  
or on a wet surface; either situation could cause an  
electric shock.  
Always press the on/off switch down to switch off the  
compressor before switching off the power or removing  
the power plug.  
Always shut off the compressor after use and before  
servicing. Push the rocker on/off switch to the off position.  
Turn the power supply switch off and remove the  
electrical plug from the power supply.  
Note. The compressor does not require oil and is  
self lubricating.  
After using the compressor, switch off the on/off switch,  
connect the power supply and ensure all the air pressure  
in the tank and hose has been released.  
Check the maximum pressure rating of any tools or  
accessories that you intend using with the compressor.  
The output pressure of the air from the compressor must  
be regulated so that it never exceeds the rated pressure  
of the tool or accessory.  
Do not attempt to remove any part of the machine whilst  
it is under pressure.  
Use safety equipment including safety goggles or  
shield, ear protection, breathing or respirator mask and  
protective clothing.  
To avoid the risk of burns and injury from moving parts,  
do not operate the compressor with out the compressor  
being fully intact or without the safety shield. Allow hot  
parts to cool before handling or servicing.  
Wear goggles  
Wear earmuffs  
Be certain to read all the labels on the containers of paint  
or other materials to be sprayed. Closely follow all safety  
instructions. Use a respirator mask if there is a chance  
that you might otherwise inhale the spray material.  
Carefully check the effectiveness of any respirator mask  
you intend using.  
Wear a breathing mask  
Never apply the outlet air of this compressor directly on to  
any part of a person’s body. Do not attempt to block the  
air outlet with your finger or any part of your body.  
The tool must be used only for its prescribed purpose.  
Any use other than those mentioned in this Manual will  
be considered a case of misuse. The user and not the  
manufacturer shall be liable for any damage or injury  
resulting from such cases of misuse.  
Always wear safety goggles or glasses when using the  
air compressor. Never point the nozzle of an accessory  
towards any part of your body or towards another person.  
Do not attempt to adjust the pressure switch.  
The manufacturer shall not be liable for any changes  
made to the tool nor for any damage resulting from  
such changes.  
Drain the moisture from the tank daily. It will help  
prevent corrosion.  
Pull the ring on the safety valve daily to ensure that it is  
operating properly and to clear any possible blockages.  
Even when the tool is used as prescribed it is not  
possible to eliminate all residual risk factors.

The following hazards may arise in connection with the  
tool’s construction and design:  
Damage to the lungs if an effective breathing mask is  
not worn.  
Damage to hearing if effective earmuffs are not worn.  
Damage to the eyes if effective safety goggles or shield  
are not worn.  
WARNING. In the event that an air line is cut or broken,  
the air line needs to be immediately disconnected from  
the compressor at the quick release fitting. This will  
automatically stop the air from free flowing. A broken air  
line which is not supported is extremely dangerous and can  
whip around very quickly, both with the capability of striking  
people, and blowing foreign particles into the air.  
Do not attempt to catch the air line but immediately keep  
bystanders well clear. Disconnecting the remaining hose  
from the quick release fitting on the unit will automatically  
shut off the air supply. Turn off the compressor at the On /  
Off rocker switch.  
Unpacking  
Due to modern mass production techniques, it is unlikely  
that your GMC Power Tool is faulty or that a part is missing.  
If you find anything wrong, do not operate the tool until the  
parts have been replaced or the fault has been rectified.  
Failure to do so could result in serious personal injury.

Problem  
Possible cause  
Suggested remedy  
Air fittings leaking.  
Check all air fittings. Make sure that  
they are tight and not leaking at the  
joins. If a quick release fitting is leaking,  
disconnect it and reconnect it. If it  
continues to leak replace the defective  
fitting(s). If a male or female fitting  
is leaking around the thread tighten  
using a spanner. If the fitting is already  
tight and can’t be tightened anymore  
unscrew the connection, remove the  
Teflon tape and look at the condition  
of the fitting(s). If the a fitting(s) is  
damaged replace and reassemble  
using Teflon tape on threaded fittings.  
If the fitting looks OK or reapply Teflon  
tape and re assemble.

WARNINGS.  
Maintenance  
Safety glasses must be worn when performing this test.  
1. After each day of operation,  
use the drain cock (13) under  
the tank to drain out any  
condensation (Fig. O).  
O
Do not have your face close to the safety valve when  
performing this test as air will discharge from the valve at a  
high force.  
2. After each day of operation  
check daily the operation of  
the safety valve (10). This  
check should be performed  
when the tank contains close  
to max pressure.  
If the safety valve does not operate correctly in any way as  
described above, turn off the compressor immediately and  
have the compressor and safety valve checked and tested  
at an authorised Service centre.  
DO NOT CONTINUE TO USE THE COMPRESSOR IN  
ANY WAY IF THE SAFETY VALVE DOES NOT WORK  
AS ABOVE.  
To check the valve, pressurise the tank, and pull the  
ring OUTWARDS on the safety valve.  
General inspection  
1. Regularly check that all the fixing screws are tight.  
2. The supply cord of the tool should be checked frequently  
for damage. If damaged, have the cordset replaced by an  
authorised service facility to avoid a hazard.  
Air should discharge from the valve.  
Release the ring of the safety valve. When the ring is  
released the air discharge must stop.

Cleaning  
1. Keep the tool’s air vents unclogged and clean at all times.  
2. Remove dust and dirt regularly. Cleaning is best done  
with a soft brush or a rag.  
3. Re-lubricate all moving parts at regular intervals.  
4. If the body of the compressor needs cleaning, wipe it  
with a soft damp cloth. A mild detergent can be used but  
nothing like alcohol, petrol or other cleaning agent.  
5. Never use caustic agents to clean plastic parts.  
CAUTION. Water must never come into contact with  
the tool.
